Isaiah 53:5: But he was wounded for our transgressions, he was bruised for our iniquities; upon him was the chastisement that made us whole, and with his stripes we are healed.

St. Teresa of Avila and The Battle with evil

From The Collected Works of St. Teresa of Avila, Volume 1, Chapter 31, parts: 7-11 :

7. It is certain that what I shall now tell happened to me. (And there are many witnesses to this, especially the one who is now my confessor since he saw it written in a letter; without my telling him who the person was to whom the letter belonged, he knew very well who it was.)

A person came to me who had been in mortal sin for two and a half years. It was one of the most abominable I've heard of, and in all this time he hadn't confessed or made amends; and he was saying Mass. Although he was confessing other sins, of this one he asked how he could confess something so ugly. He had a great desire to give it up, but he wasn't able to help himself. He made me feel great pity, and my seeing that he offended God in such a way caused me deep sorrow. I promised him I would beg God very much to liberate him and that I would get others better than myself to do the same, and I wrote to him through a certain person he told me I could give the letters to. And so it happened that after receiving the first letter he went to confession. For God desired (through the many very holy persons to whose prayers I recommended him) to grant this soul that mercy; and I, although miserable, did what I could with great care. He wrote to me that he was so much better that for days he had not fallen into the sin, but that the torment the temptation gave him was so intense it seemed from what he suffered he was in hell; he asked me to commend him to God. I in turn recommended him to my sisters through whose prayers the Lord must have granted me this favor, for they took the matter very much to heart. No one could guess who the person was. I begged His Majesty to mitigate those torments and temptations and that those devils would come to afflict me, provided that I would not offend the Lord in anything. As a result, for a month I suffered severe torments; it was during this time that these two things I mentioned happened.

8. The Lord was pleased that they leave him; this he wrote to me, for I told him what I was going through during that month. His soul was fortified, and he was left completely free. He didn't have enough of thanking God and me as though I had done anything. But the reputation I had from the fact that the Lord granted me favors benefitted him. He said that when he found himself very distressed he read my letters, and the temptation left him. He was very impressed by what I had suffered and how he had been freed. Even I was amazed, and I would have suffered many more years to see that soul free. May the Lord be praised for everything, for the prayer of those who serve Him (as I believe do these sisters in this house) can do much. But since I sought these prayers, the devils must have been more angry with me; and the Lord on account of my sins permitted this.

9. Also one night during this time I thought they were choking me; after much holy water had been sprinkled around, I saw a great multitude of them go by, as though they were being thrown down a precipice. There are so many times that these cursed creatures torment me, and so little is the fear I now have of them, seeing that they cannot stir unless the Lord allows them, that I would tire your Reverence and tire myself if I told about all these instances.

10. May what was said be of help that the true servant of God might pay no attention to the scarecrows the devils set up in order to cause fear. We should know that each time we pay no attention to them they are weakened and the soul gains much more mastery. Some great benefit always remains, which I won't go into so as not to enlarge. I shall only mention what happened to me on the night of All Souls: while I was in the oratory after having recited a nocturn and while saying some very devotional prayers that come at the end, a devil appeared on the book so that I couldn't finish the prayer. I blessed myself, and he went away. When I began again to recite the prayers, he returned. I believe it was three times I began, and until I threw holy water at him I couldn't finish. I saw that some souls left purgatory at that instant; little must have been lacking to their freedom, and I wondered if he had aimed at preventing this.

A few times I've seen him in physical form, but many times with no physical form-as for instance in the vision mentioned above in which without seeing any form one knows he is there.

11. I also want to tell the following because it frightened me a lot: one day on the feast of the Trinity, being in the choir of a certain monastery and in rapture, I saw a great battle of devils against angels. I couldn't understand what that vision meant. In less than fifteen days it became easily understandable on account of a certain conflict that arose between people of prayer and many who were not, and a lot of harm was done in the house in which it took place. It was a battle that lasted a long time and caused much disquiet.

At other times I saw a large multitude of devils around me, and it seemed that a great brightness encircled me, and this prevented them from reaching me. I understood that God was watching over me so that they could not get to me in order to make me offend Him. From what I sometimes saw in myself, I understood that it was a true vision. The fact is that now I have understood so well the little bit of power he has provided I'm not against God, that I have almost no fear . The powers of devils are nothing if these devils do not find souls cowardly and surrendered to them: it is with such souls that they show their power. Sometime, in the temptations I already mentioned, it seemed to me that all the vanities and weaknesses of the past were again awakening within me; I had really to commend myself to God. At once the torment came of thinking that since those thoughts arose in me the favors I experienced must all be from the devil. It seemed to me that there shouldn't have been even the first stirrings of a bad thought in one who was receiving so many favors from the Lord. But then my confessor put me at peace.

The Collected Works of St. Teresa of Avila, Volume 1, Chapter 31, part 4.

I often experience that there is nothing the devils flee from more without returning than holy water. They also flee from the cross, but they return. The power of holy water must be great. For me there is a particular and very noticeable consolation my soul experiences upon taking it. Without a doubt my soul feels ordinarily a refreshment I wouldn't know how to explain, like an interior delight that comforts it entirely. This isn't some fancy or something that has happened to me only once, but something that has happened often and that I've observed carefully. Let us say the relief is like that coming to a person, very hot and thirsty, when he drinks a jar of cold water; it would seem that he felt the refreshment all over. I consider everything ordained by the Church to be important, and I rejoice to see the power of those words recited over the water so that its difference from unblessed water becomes so great.

* Let us pray for our Priests and not criticise them or condemn them. We can see above in St. Teresa's writings the power of Praying for Priests and that the Lord wants us to pray much, offer sacrifices and intercede for them regularly.

Excerpts of the Pope's Sermon on the Feast of the Sacred Heart 2010

The most important of those texts in today’s liturgy is Psalm 23(22) – “The Lord is my shepherd” – in which Israel at prayer received God’s self-revelation as shepherd, and made this the guide of its own life. “The Lord is my shepherd, I shall not want”: this first verse expresses joy and gratitude for the fact that God is present to and concerned for us. The reading from the Book of Ezechiel begins with the same theme: “I myself will look after and tend my sheep” (Ez 34:11). God personally looks after me, after us, after all mankind. I am not abandoned, adrift in the universe and in a society which leaves me ever more lost and bewildered. God looks after me. He is not a distant God, for whom my life is worthless.

Another part of this sermon

“Your rod and your staff – they comfort me”: the shepherd needs the rod as protection against savage beasts ready to pounce on the flock; against robbers looking for prey. Along with the rod there is the staff which gives support and helps to make difficult crossings. Both of these are likewise part of the Church’s ministry, of the priest’s ministry. The Church too must use the shepherd’s rod, the rod with which he protects the faith against those who falsify it, against currents which lead the flock astray. The use of the rod can actually be a service of love. Today we can see that it has nothing to do with love when conduct unworthy of the priestly life is tolerated. Nor does it have to do with love if heresy is allowed to spread and the faith twisted and chipped away, as if it were something that we ourselves had invented. As if it were no longer God’s gift, the precious pearl which we cannot let be taken from us. Even so, the rod must always become once again the shepherd’s staff – a staff which helps men and women to tread difficult paths and to follow the Lord.

From the Catechism..

The Holy Eucharist

1324 The Eucharist is "the source and summit of the Christian life."136 "The other sacraments, and indeed all ecclesiastical ministries and works of the apostolate, are bound up with the Eucharist and are oriented toward it. For in the blessed Eucharist is contained the whole spiritual good of the Church, namely Christ himself, our Pasch."137

Quote

Our Lord Jesus to St. Faustina - My daughter, just as you prepare in My presence, so also you make your confession before Me. The person of the priest is, for Me, only a screen. Never analyse what sort of a priest it is that I am making use of; open your soul in confession as you would to Me, and I will fill it with My light. (1725)
